problem copying knoppix kernel to hard drive

hey everyone,

I'm using arch linux on my hard drive and I am unable to get pci hotplugging to work.
A knoppix-std live cd that I have IS able to get things to work, so I thought I would copy the knoppix-std bzImage, System.map, and config files over to my arch-linux hardrive.

I am inserting the kernel image, config, System.map from the knoppix-std livecd into my hd's /boot directory and I am configuring my grub config file to boot THAT kernel image INSTEAD.

When booting up into knoppix' kernel image, I get the message that there is a kernel panic and that I need to change my "root=" statement, so I'm not sure what I should do.

here is some information that I thought might be relevant
- the knoppix cd that I am using is knoppix-std with a 2.4.21 kernel
- the arch linux on my hardrive is using 2.4.31 kernel
- the knoppix files that I copied to my /boot directory are named 2.4.21-xfs, System.map-2.4.21-xfs, config-2.4.21-xfs.old
- does this mean that I need to be using the xfs filesystem?

In theory this should work, shouldn't it?
does anyone have any experiece with this?
